FIG. 3 is an operation explanatory diagram of the second workpiece moving mechanism.
(A) is a second process of moving the processedsecond workpieces 18b and 18b within the robot movement range to the outside of the protective fence in parallel with the work when the first workpiece is worked by the robot. It is a figure explaining a workpiece taking-out process. In this step, the worker P grasps and pulls out theoperation unit 48 of thetray 43 and takes out the processedsecond workpieces 18b and 18b.

(b)は、保護柵の外から未処理の第2ワーク18a、18aをロボットの動作範囲へ移動する第2ワーク投入工程を説明する図である。この工程において、作業者Pは、未処理の第2ワーク18a、18aをトレイ43に入れ、この操作部48をつかんで押し、第2ワーク18a、18aをロボット11の動作範囲内に移動させる。

この工程において、ロボットで第2ワーク18a、18aにシール剤塗布作業を施す。
このとき、トレイ43が完全に閉じている条件にのみ、動作範囲Kで且つ保護柵21の基台41上に移動でき、それ以外の条件では、基台41上に侵入しないようにロボット11の動きを制御する。
(B) is a figure explaining the 2nd workpiece | work injection | throwing-in process which moves unprocessed 2nd workpiece |work 18a, 18a from the outside of a protection fence to the operating range of a robot. In this step, the worker P puts the unprocessedsecond workpieces 18 a and 18 a in thetray 43, grasps and pushes theoperation unit 48, and moves thesecond workpieces 18 a and 18 a within the operation range of therobot 11.
(C) is a figure explaining the 2nd work process which works with the2nd work 18a, 18a with a robot, when it does not overlap with the 1st work process.
In this step, the robot applies a sealant application operation to thesecond workpieces 18a and 18a.
At this time, only when thetray 43 is completely closed, therobot 11 can move on thebase 41 of theprotection fence 21 within the operating range K. In other conditions, therobot 11 can be prevented from entering thebase 41. Control movement.

図4は本発明に係る作業装置のタイムチャートであり、横軸は時間を示す。
ロボットによる作業方法は、ロボットが第1ワークに作業を施す第1作業工程と、この工程に並行して処理済みの第2ワークを保護柵の外へ移動する第2ワーク取り出し工程と、保護柵の外から未処理の第2ワークをロボットの動作範囲へ移動する第2ワーク投入工程と、第1作業工程と重ならないときに、第2ワークに前記ロボットで作業を施す第2作業工程と、第2作業工程と並行して第1コンベヤでパレットを移動させ、加工済みの第1のワークを払い出すとともに未加工の第1のワークを動作範囲内における所定の位置に搬入するパレット移動工程とからなる。
FIG. 4 is a time chart of the working device according to the present invention, and the horizontal axis indicates time.
The robot working method includes a first work process in which the robot performs work on the first work, a second work take-out process in which the processed second work is moved out of the protective fence in parallel with this process, and a protective fence. A second workpiece input step of moving an unprocessed second workpiece from outside the robot to an operation range of the robot, a second operation step of performing an operation on the second workpiece by the robot when not overlapping with the first operation step, A pallet moving step in which the pallet is moved by the first conveyor in parallel with the second work step, the processed first workpiece is discharged, and the unprocessed first workpiece is carried to a predetermined position within the operation range; Consists of.

このような方法を採ることで、第1ワークの搬送時などロボットが第1ワークにシール剤塗布作業をしないときのロボットの待ち時間を、第2ワークの作業に振り向けることができる。
すなわち、第1作業工程と重ならないときに、第2ワークにロボットで作業を施す第2作業工程を備え、第1ワークと第2ワークを共通のロボットで連続的に処理するようにしたので、ロボットの稼働率を向上することができ、ロボットを有効に活用することができる。
By adopting such a method, the waiting time of the robot when the robot does not apply the sealant to the first workpiece such as when the first workpiece is transferred can be directed to the operation of the second workpiece.
That is, when it does not overlap with the first work process, it has a second work process in which the second work is performed by a robot, and the first work and the second work are continuously processed by a common robot. The operating rate of the robot can be improved, and the robot can be used effectively.

本実施例において、第1ワーク(図2の符号15)はエンジンのシリンダブロックであり、第2ワーク(図2の符号18)は同一のエンジンに用いる小物部品であり、これらを1つのシール剤塗布ユニットで処理することができる。また、シール剤を塗布した後のワークは、シール剤が固まる前に組み付けることが必要なものである。いわゆる、ワークの造り溜めは許されず、速やかに組付作業をさせる必要があった。本発明の作業装置は、このような条件の下での生産に好適である。  In this embodiment, the first work (reference numeral 15 in FIG. 2) is a cylinder block of the engine, and the second work (reference numeral 18 in FIG. 2) is a small part used in the same engine. It can be processed in a coating unit. Moreover, the workpiece | work after apply | coating a sealing agent needs to be assembled | attached before a sealing agent solidifies. So-called work accumulation was not allowed, and it was necessary to promptly perform assembly work. The working device of the present invention is suitable for production under such conditions.

図2に戻って、保護柵21に、第2ワーク18を載せ、保護柵21の外からロボット11の動作範囲Kへ移動させる第2ワーク移動機構19が付設されている。
仮に、ロボット11に人を介在させる作業を含んでいる場合、ロボット11の稼働率をできるだけ低下させないようにするため、扉の開閉検出手段及びロボット11の周囲にセンサなどの要素を設け、所定の条件を満たしたとき一部の範囲でのみ人を介在させる。このため、ロボット11の稼働率の低下は回避できるものの、作業者Pを保護する要素が増え、作業装置10は複雑なものにならざるを得ない。
Returning to FIG. 2, a secondworkpiece moving mechanism 19 is provided for placing thesecond workpiece 18 on theprotective fence 21 and moving it from the outside of theprotective fence 21 to the operation range K of therobot 11.
If therobot 11 includes an operation of interposing a person, an element such as a sensor is provided around the door opening / closing detection means and therobot 11 in order to prevent the operation rate of therobot 11 from being reduced as much as possible. Intervene only in certain areas when the conditions are met. For this reason, although a decrease in the operation rate of therobot 11 can be avoided, the number of elements for protecting the worker P increases, and thework apparatus 10 has to be complicated.

この点、本発明では、保護柵21に、第2ワーク18を載せ、保護柵21の外からロボットの動作範囲Kへ移動させる第2ワーク移動機構19を付設するので、ロボット11の動作範囲に作業者Pを介在させない作業装置を構成することが可能となる。動作範囲に作業者を介在させることのない作業装置を構成することができる。  In this regard, in the present invention, since thesecond work 18 is placed on theprotection fence 21 and moved from the outside of theprotection fence 21 to the movement range K of the robot, the movement range of therobot 11 is increased. It is possible to configure a working device that does not involve the worker P. It is possible to configure a working device that does not involve an operator in the operating range.

すなわち、人が保護柵21内に入らないで、ロボット11に第2ワーク18へ作業を行わせることができる。
作業者が保護柵内に入る必要がないので、作業者を検出するセンサやスイッチを省くことができ、簡便な構造をもち、低廉な費用で構成可能な作業装置を提供することができる。
That is, therobot 11 can cause thesecond work 18 to perform an operation without a person entering theprotective fence 21.
Since it is not necessary for the worker to enter the protective fence, a sensor or switch for detecting the worker can be omitted, and a working device that has a simple structure and can be configured at low cost can be provided.

尚、本発明は、実施の形態ではシリンダブロックのシール剤塗布装置に適用したが、車体組立工程における、ドア部材及び小物部品へのシール剤塗布に適用可能であり、それ以外の一般の生産ライン上において、ワークにシール剤を塗布する工程に適用することは差し支えない。  Although the present invention is applied to the cylinder block sealant application device in the embodiment, it can be applied to the door member and small parts applied in the vehicle body assembly process, and other general production lines. In the above, it may be applied to the process of applying the sealing agent to the workpiece.

本発明は、エンジンの製造工程における、シリンダブロックのシール剤塗布装置及びその作業方法に好適である。  INDUSTRIAL APPLICABILITY The present invention is suitable for a cylinder block sealant coating apparatus and its working method in an engine manufacturing process.
